Average length of your campaign games?

hey guys I am doing a little research.

I would like to know how long TWC players play one campaign on average before quitting and switching to a new campaign.
I personally find the game boring after post turn 100ish and start a new campaign.
so, tell me, how long do your average games last?
this is a across the board research on all TW games released so far, please try to avoid voting a second time in the a similar poll and please vote, it wont matter if the sample is too small!

It takes me like 30 or 40 turns to conquer every region in Napoleon, on hard. Less than that to take the required regions and win the campaign.

i like to develop slowly and not to go on a war frenzy by backstabbing allys and things like that, so i usually take a lot more time, maybe 100 turns. If i decide to do it fast i can do it in 30 to 60 turns, depending if i get lucky...
